Abstract

The present invention discloses a one-way grade separation overpass which is composed of a central overpass way and slip roads leading to circumambience, wherein each slip road can be orderly divided into four smooth running ways and four reverse running ways. Smooth running right turn, straight running and left turn are respectively communicated with a reverse running carriageway corresponding to right adjacence, opposite direction and left adjacence. A carriageway for turning back directly turns, left turn and right turn carriageways are mutually and horizontally staggered, and meeting points of smooth running and reverse running carriageways are respectively staggered up and down in a grade separation mode. The interpenetration design of the central overpass way causes carriageway lines to be in crossed detour but not in intersection, which ensures that each carriageway line is unimpeded, and reduces the hidden danger that a traffic jam causes accidents.

The purpose of this invention is to provide a kind of one-way gallop bridge, the UNICOM of itself and peripheral direction carriage way is rule but also do not cross mutually not only, and motor vehicle and bicycle are isolated and travelled, and can effectively ensure the smooth and easy without hindrance of driving.

Summary of the invention

For achieving the above object, the present invention takes following design scheme: this one-way gallop bridge, the road that leads to four direction by center bridge circuit and UNICOM of institute is formed, each to road be provided with according to the order of sequence respectively that direct motion is turned right, keeps straight on, turned left, the revolution and the revolution of driving in the wrong direction, eight divided lanes of keeping straight on, turn left, turn right, wherein:

A, each retrograde left and right changing trains or buses to the left and right left and right neighborwise road of changing trains or buses to lead to respectively of the direct motion at road junction;

B, each leads to the retrograde direct lane of opposite direction to the direct motion direct lane at road junction;

C, each to the direct motion at road junction revolution directly revolution lead to the retrograde revolution track of this road;

D, suitable, the contrary track that will cross independently separately form four joints;

Above-mentioned each cross laterally each track forward to the direct motion left turn lane of road, the mutual offset of changing trains or buses about each;

The joint in direct motion and each track of driving in the wrong direction staggers up and down respectively in the graded crossing mode.

The invention will be further described below in conjunction with drawings and Examples.

The specific embodiment

As shown in Figure 1, solid line is represented direct lane, chain-dotted line is represented left turn lane (arrow is oppositely then represented the right-turn lane of another embodiment), the dotted line representative is turned right (arrow is oppositely then represented the left turn lane of above-mentioned another embodiment) and the revolution track, the mutual joint in each track of expression in the circular lines, each changes trains or buses to cross forward laterally each track, each left and right mutual offset of changing trains or buses to the direct motion left side (right side) of road; The joint in direct motion and each track of driving in the wrong direction staggers up and down respectively in the graded crossing mode, can realize without hindrance current.

Embodiment 1

Fig. 2 is a specific embodiment structural representation, the present invention is by center transit bridge zone and lead to road A all around, B, C, D forms, each to road by being defined as the direct motion (A1 that turns right from right to left successively, B1, C1, D1), (A2 keeps straight on, B2, C2, D2), (A3 turns left, B3, C3, D3), revolution (A4, B4, C4, D4) reach revolution (A ' 4 of driving in the wrong direction, B ' 4, C ' 4, D ' 4), craspedodrome (C ' 2, D ' 2, A ' 2, B ' 2), left-hand rotation (B ' 3, C ' 3, D ' 3, A ' 3), right-hand rotation (D ' 1, A ' 1, B ' 1, C ' 1) eight tracks, with the A track is example, direct motion right-hand rotation A1 directly turns right and leads to the retrograde right-hand rotation A ' 1 of right neighboring trace, retrograde direct lane A ' 2 UNICOMs in direct motion direct lane A2 and opposite direction track, retrograde left-hand rotation A ' 3 UNICOMs of direct motion left-hand rotation A3 and left neighborwise road, directly turn around the away retrograde revolution A ' 4 in this track of direct motion revolution track A4, other road also is same rule.For each is not crossed mutually to craspedodrome and left turn lane of road, need in central area design transition bridge section, both each to keep straight on and left turn lane elder generation upward slope road and bridge descending again pass horizontal track bridge circuit after, sensible destination separately makes a circulation not cross mutually and realize interting.

Embodiment 2:

Principle is the same, as shown in Figure 3, each to the track be defined as successively oppositely from left to right that direct motion is turned left, keeps straight on, turned right, the revolution and the revolution of driving in the wrong direction, eight divided lanes of keeping straight on, turn right, turn left.

Embodiment 3:

Principle is with embodiment 3, and difference is: each is worn to go up a slope under craspedodrome and left turn lane elder generation again and passes horizontal track bridge circuit, as shown in Figure 4.

Embodiment 4,5:

With reference to Fig. 5, shown in Figure 6, be the moulding of two kinds of different structure forms of overpass bridge, the former is a unidirectional bridge construction of avoiding joint, and the latter isolates by overhead form and nonmotorized vehicle lane, and realization interts and does not cross mutually.

Consider when vehicle moves ahead, by two-way and to a Louis bump against, the obstruction accident, do not have this phenomenon generation and be divided into two-way by one the tunnel, so each can be united two into one to the parallel highway section of craspedodrome of the ground at road junction and left-hand rotation leading portion zone, passing adjacent bridge following time is divided into two the tunnel again and leads to the destination, each road junction can be kept to Qi Tiaolu with former eight like this, and bridge circuit also can be single line, the area that can more minimizing overpass bridges takies.

The technical solution of the present invention one is considered the current of motor vehicle, its two consideration bicycle and pedestrian's key element, then all the people present master's bridge and guiding bridge circuit can be erected, form the viaduct of main bridge and guiding bridge construction, or with bicycle and pavement be made as underground form all can realize motor vehicle and bicycle mutually fully isolation can pass through the crossing simultaneously again.

The overpass bridge of technical solution of the present invention design, the tactical rule compactness, well arranged also few, be beneficial to construction, take up room and land area few, be suitable for the circumstances construction of multiple crossing, and concerning comrade driver,, need not go one by one direction because each is consistent to the road travel rule, as long as remember primitive rule, its maximum advantage is that also this bridge is avoided crossing of various vehicles and realized using Correct Lane of vehicle in the mode of interspersed jump mutually, does not disturb mutually, reduced the hidden danger that traffic jam, accident take place, for modernized city life has been accelerated paces.
